Traction wheel



K. J. E. NILSON TRACTION WHEEL Nov. 16, 1937.

Filed Feb. 19, 1936 Patented Nov. 16, 1937 UNITED STATES PATENT ()FFECE3 Claims.

This invention relates to new and useful improvements in tractionwheels, and it has for its object to provide a construction which willmake it possible to use a motor sled with no diminishing effect as tospeed and manipulation on account of the condition of the ground, orroad, that is, whether the latter is covered by ice or snow.

Thus this present invention may be said in some respects to be animprovement on, and Variation of an invention, for which the U. S.patent, No. 1,574,924, has been granted to me.

As my new construction is comparatively simple, the cost ofmanufacturing should be proportionately low.

With the above and other objects in View, this invention consists of thenovel features of construction, combination and arrangement of partshereinafter fully described, claimed and illustrated in the accompanyingdrawing forming part of this application, and in which similarcharacters of reference indicate corresponding parts in all views, andin which:

Figure 1 shows in detail and detached a shoe member, a number of whichare secured to the front wheel of my device.

Figure 2 shows, in part, my said shoe device secured to a wheel; whileFigure 3 shows, in detail, the relative arrangement of one of said shoesupon a wheel; and

Figure 4 represents another view, in detail, of the shoe proper.

Referring more particularly to the drawing, a single unit, or shoemember has been shown detachedin Figure 1, while the relativearrangement of a shoe member to the wheel has been shown in Figure 3,and a number of shoe members have been shown attached to part of a wheelin Figure 2.

The said shoe member comprises a downwardly depending bifurcated portion2|, each side of which portion is provided with an aperture 22 adaptedto receive therein a screw or rivet 23, when, as shown in Figure 2, theshoe is attached to the edge of the wheel 20. The opposite end of saidbifurcated portion terminates in a gripping member 2d, which consists ofa block portion cut out in a substantial H-shaped form in order to givethis part durability and strength, and at the same time provide saidpart with as many sharp engaging edges as possible, without, as saidabove, weakening the strength of the construction. While said grippingmember may be made integral with the bifurcated portion, it may also bemade as a special unit provided with a shank, which may then be threadedinto, or in any other way secured to said bifurcated section.

A Vshaped tapered portion 25 forms an integral part of said shoe member,while short rods 26, 26, only one of which can be seen in Figure 1,depend from said V-shaped member near the free ends thereof, and arealso made integral with the latter. At the lower end of each rod 26 andforming an integral part therewith, is a short cylindrical tube 21formed with collars 44 thereon and, adapted to be fastened on to thewheel proper, one tube upon each side thereof, while a bolt, or rivet28, secures said tube members integrally to the wheel, as shown inFigure 2.

It will appear evident that by mounting said shoe system upon a wheel,as described, said wheel will take any snowy and icy road, as theH-shaped and V-shaped members consisting the main characteristics ofsaid shoe, will in turn engage and form a solid grip upon any snowy andicy road.

It is obvious that changes may be made in the form, construction andarrangement of the several parts, as shown, within the scope of theappended claims, without departing from the spirit of the invention, andI do not therefore wish to limit myself to the construction andarrangement shown and described herein.

What Iclaim as new, and desire to secure by Letters Patent of the UnitedStates, is:

1. In a device of the class described, a traction wheel, shoe membersmounted upon the edge of the latter and comprising a bifurcated bodyportion, a sharp-edged block member opposite said bifurcated portion andthreaded into the latter, a V-shaped tapered section integral with saidbifurcated portion, short rods depending from and integral with saidV-shaped portion, and short cylindrical tubes integrally secured at thelower ends of said rods and adapted for attachment to the peripheraledge of said wheel.

2. In a device of the class described, a traction wheel, shoe membersmounted upon the edge of the latter and comprising a substantiallyHshaped, sharp-edged gripping member, a bifurcated section adjacent saidgripping member and attached thereto, the forked sections of thebifurcated member being formed with apertures therein for securing saidsections to the wheel, a substantially V-shaped, tapered sectionintegral with said former parts, a rod integral with and depending fromeach wing of said V-shaped member, and short cylindrical tubes formingan integral part with said rods, and being adapted to engage the edgeportion of the wheel, and fastening means for securing said tubes to thelatter, substantially as shown and. described.

3. In a device of the class described, a traction Wheel, shoe membersmounted upon the edge of the latter and comprising a bifurcated bodyportion, a sharp-edged block member opposite said bifurcated portionthreaded into the latter, a V-shaped tapered section integral with saidbifurcated portion, and means for securing said V-shaped member to theedge of a wheel, substantially as and for the purpose set forth.
